Start up your Mac in Windows or macOS

You can set the default operating system, either Windows or macOS, that you use to start up your Mac.

Set the default operating system

Click in the right side of the taskbar, click the Boot Camp icon , then choose Boot Camp Control Panel.

If a User Account Control dialog appears, click Yes.

Select the startup disk that has the default operating system you want to use.

If you want to start up using the default operating system now, click Restart. Otherwise, click OK.

You can’t change your startup volume to an external FireWire or USB drive while you’re using Windows. To learn how to change the default operating system using macOS, see Set the default operating system.
